Capitalized Software Development Costs Under a Hosting Arrangement

The Company accounts for the cost of computer software obtained or developed for internal use as well as the software development and implementation costs associated with a hosting arrangement ("internal-use software") that is a service contract in accordance and with ASC 350, Intangibles - Goodwill and Other ("ASC-350"). The Company capitalizes certain costs in the development of our internal-use software when the preliminary project stage is completed and it is probable that the project itself will be completed and the software will perform as intended. These capitalized costs include personnel and related expenses for employees and costs of third-party consultants who are directly associated with and who devote time to these internal-use software projects. Capitalization of these costs ceases once the project is substantially complete and the software is ready for its intended purpose. Costs incurred for significant upgrades, increased functionality, and enhancements to the Company's internal-use software solutions are also capitalized. Costs incurred for training, maintenance, and minor modifications are expensed as incurred. Capitalized software development costs are amortized using the straight-line method over an estimated useful economic life of three years.
